Title: Air-core coil for high-frequency circuit
Inventor: OSADA SHIGERU
IPC: H01F17/02
Filed: 2001-09-12
Abstract: PROBLEM TO BE SOLVED: To provide an air-core coil for high-frequency circuit which is suitable for physically thinner circuit and assures easy adjustment of the circuit. SOLUTION: The air-core coil for high-frequency circuit comprises a winding portion 4, which is formed by winding two conductor wires 2, 3 in parallel and connecting portions 5a, 5b provided at the end part of the winding portion 4. Since two conductor wires 2, 3 are wound with each other under the parallel condition to a center line C1 of the winding portion 4 and have the connecting portions 5a, 5b where two conductor wires 2, 3 located at the end part are connected, the air-core coil 1 is formed of a bifilar wire and diameter A1 of the conductor wires 2, 3 can be set narrower than a diameter A2 of a conventional conductor wire 22. Therefore, height of the winding portion 4 of the air-core coil 1 can be set smaller than the conventional one from the surface of a printed circuit board 6. Accordingly, the air-core coil for high-frequency circuit which is desirably applied to the physically thin circuit can be obtained.

IPC: G11B20/10
Filed: 2001-09-13
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of recording (reproduction) by predicting a buffer over error (short error) in recording (reproduction). SOLUTION: A control circuit temporarily suspends the recording (reproduction), when a data residence residue determined based on a difference between a data position at which data is transmitted to a circuit on a data input/output side on a buffer and a data position at which data is transmitted to a disk drive dips from (exceeds) a preset threshold in recording (reproduction). The control circuit performs a seek process for seeking a light spot to a track in suspension, then predicts whether the buffer has the over error (short error), or whether the buffer has the over error (short error) when the light spot reaches a recording (reproduction) restarting address on the track on which the light spot indicates a position for restarting the recording (reproduction).  When the error is predicted, re-seeking to a seek target address determined based on the data residence residue is performed.

Title: Cryptographic key updating method
Inventor: HAGITA MARIKO
IPC: H04L9/16
Filed: 2001-10-01
Abstract: PROBLEM TO BE SOLVED: To reduce a processing time and communication costs for updating a key in cipher communication. SOLUTION: The user of the cipher communication first exchanges and shares a basic key (k) by a Diffie-Hellman key exchange system or the like. The size of the basic key (k) is kept larger than that of a cryptographic key. Cryptographic keys (g) are respectively separately generated from the basic key (k) according to the same one directional function. After the end of the communication, key updating is executed for the next cipher communication. Only by the first basic key exchange, an i-th cryptographic key g(k, i) is generated without performing communication for cryptographic key updating after that. Key updating can be executed after the end of communication and a waiting time and communication costs during communication for key updating can be reduced.  Identity is also proved by enabling the generation of the next cryptographic key and a role as authentication can be obtained as well.
